Rigrodsky
& Long, P.A. announces that it is investigating potential legal
claims against the board of directors of National Interstate Corporation
(“National Interstate” or the “Company”) (NASDAQ GS: NATL)
regarding possible breaches of fiduciary duties and other violations of
law related to the proposed acquisition of the Company by its largest
shareholder, Great American Insurance Company, a subsidiary of American
Financial Group, Inc. (NYSE: AFG),
through a tender offer.

Under the terms of the transaction, public shareholders of National
Interstate can elect to receive $28.00 per share in cash for each share
of National Interstate they own.

The investigation concerns whether National Interstate’s board of
directors breached its fiduciary duties to the Company’s shareholders
and whether the proposed consideration to be paid to the Company’s
shareholders is fair and adequate.

If you own the common stock of National Interstate and purchased your
shares before February 5, 2014, if you have information or would like to
learn more about these claims, or if you wish to discuss these matters
or have any questions concerning this announcement or your rights or
interests with respect to these matters, please contact Seth D.
